M-140
FEATURES
- Wide range of current measurements (AC 0.01A〜300A).
M-310
FEATURES
- The unique “U” type direct touch CT enables to measure the current of single & three phase circuit just by touching the conductors and
it is suitable for the AC current measurement of narrow & congested circuit.
M-110
FEATURES
- Model 110 is a clamp-on type ammeter which is least affected by external magnetic fields.
- 30 ㎜ φ CT enables the leakage current measurement for SV cable (38㎡).
- data hold function especially useful when working in dark or hard to get areas.
- Pocket sized and light weight.
M-340
FEATURES
- Model 340 is a clamp-on type ammeter which is least affected by external magnetic fields.
- Enabled high resolution measurement with 40 ㎜φ CT by our new CT technology.
